Vinay sir is the coolest physics professor I have ever seen. He is caring and very friendly. His clarity in concepts is very deep. He teaches even the most tricky concepts in a very simple and easy way. He is approachable and helps in clearing all kinds of doubts, whether silly or tricky. He is very calm and collected. This is a very important and necessary quality, I believe, to think productively. Overall, he is one of the best physics professors I have ever seen. Thank you Vinay sur for guiding me in this beautiful journey.
